As here shown, the component parts oi" the machine are mounted upon the bed or trame 30. The machine is driven by an electric motor 31 disposed at one end et said vbed or table, which is belted to a countershaft 32 arranged beneath the table and which, in turn, drives a shaft 33 arranged above the bed in suitable bearings.

Clutching means are provided whereby the machine may be operably connected with the motor or disconnected at the will of the operator. Said means include a cone 3d fixed to said shaft 33 arranged in the clutched condition to lit within the tapered surface or' a pulley 35 which is loosely arranged on said shaft 33 and belted to the ;Ounter-shait 32. A clutch control lever 36 is arranged at the front ot the machine and a rod 37 is extended from said lever through. said bed 30 to a point adjacent saidpulley and terminates in a block 33, which is in engagement with a pivoted lorled lever 33 in rotatable engagement with said pulley 35. A movement oi said clutch lever 36 from one position to another position serves to regularly move saidvrod 37 to roch said pivoted lever 38 and consequently move said pulley into engagement withV the cone 34 iixed to the shaft 33 or away from engagement with said cone to thereby operably connect said shaft with the motor or disconnect it 'from the motor.

Other clutching means, shown in the drawings but not necessarily described., are provided whereby the machine may be moved, at the control of an operative, through a single complete operation.

ylhe shaft 33 is connected through gears 39 and Li0 with the shaft il which carries the cam Li2, which controls the operation of the various parts of the machine. This ar rangement oi drive from the motor to the shaft 4l provides means for reducing the speed of the motor to a valu-e suitable for the operation of the machine.

The cam Llf2 through which the various operations of the component parts oi' the machine are performed, has dwell portions 43, which permits the angular rotation ot lthe cam without operation of the mechanisin; and active portions all arranged to cause the function ot the various parts oi" the machine. During the period in which that partoi" the machine controlled by the cam is in one of said dwell portions 43, the various parts ot the machine are arranged to be in their unoperated position; and the folded material may be removed from the The rotation oi' said cam serves to re :ipro` cate said cross head between the ways, and so cause the ogeration otrhe component parts et the machine.

An operating ring il? is arranged on a raised bearing surface ot said bed'30,

and is provided with a number of extended arms 5l of suitable length, to which upright members 52 are secured, and which are formed with a suitable cam groove which serves to control the operation of certain Vranged within the groove ot the cani 42.

component parts of the mechanism. One of said uprights 52 1s formed with a gear.:

toothed portion 53, which is arranged to mesh with a rack portion 5e formed on the cross head 45. rl`he lmovement of said cross head is thereby transmitted through the rack and gear to the operating ring 49, and serves to angularly reciprocate said ring. Said ring i9 is formed with an inner con centric opening vin which is disposed a plate 55, which serves as a support for the table andthe creasing irons, which are hereinafterv to be described.

Said plate is slidably arranged on posts 56, which are secured in a frame member 57, here shown as or" substantially cross shaped form, and which is secured to the bed 30 of the machine by suitable bolts 58. The movement et said plate 55 is under the control of the operating ring, as will he hereinafter more iully described. Said plate 55., as here shown, is formed with radially extended arms 60 at right angles to each other, in which are formed the slots G1.

The material table, of which a partial sectional view is shown in Fig. 9, comprises a table portion 62 to the under side ot' which is secured downwardly extending rods 63, which are slidably arranged in the supports 611-. Springs 65 are interposed between said supports4 64; and the table, and said rods 63 are provided with nuts 65', which limit the upward movement ot' the table. Ars the machine is adapted lo operate on work ot vae rious dimensions, u separate table portion must he provided ior each different dimension ot material` this table portion comprising` the plate 62 with the downwardly extended rods 63. The supports G4 for said table are adjustably arranged in slots (il of the plate 55, the 'base oi: each support being formed with a tongue 66, which extends within the groove, and a :tlange portion 6'?,

which eilt-ends beyond the groove and in sliding engagement with the face ot the ports 64 the table construction is presser `head plate 55. AV bolt 68 serves to secure a. support 64 in adjusted lposition with respect `to said plate.

By the provision oli the aa'ljustable supmat eri all simplified and cheaped, inasmuch as the same supports may be used :for all sizes olf tables7 the only necessary new part being the table portion 62.

The material to be folded is adapted to be placed on the table 62 and to be clamped to said table by a clamping 4plate secured to the presser head, which. is arranged above ,the material table and the other component 'l parts of the apparatus and secured to the presser frame.

The presser :frame is formed as a unitary structure, hming` a rear portion G9 and the two arms 70 extending therefrom to the 7l. The presser head is arranged to support the clamping plate and the vedge :tormers or fold delining n cans. as will `be hereinafter more fully explained. Said rear portion (59 ot the presser trame is fixed to two upright rods 72, which are slidably .arranged in the base 8O olf the machine. A cross member 7d is also lined on said rods beneath the top plate of said presser frame, and carries a pin 75 which is disposed in the cam groove 7G of the up` right 52 secured to the operating ring 49. Said cam groove `is shown in detail in Fig.

The position of said member 711-, controlled by the cam groove 7 G in the upright 52 ot the operating ring, and a movement of said operating ring in such direction as to lower said cross member 7l, serves to slide the two vertical rods 72 in their bearing surfaces `in the frame olf the niachii-ie to correspondi3Y lower the presser traine fixed to said rods to cause the en sagement et' the material placed on the table 52 by the clamping plate carried by the presser head.

The machine is arranged for the folding olf ythe four sides oit the material and the four corners ot the material, and tor-this purpose is provided i Tith side wipers 77 and with corner wipers 78. Said wipers 77 and 7 8 are arranged to be moved in toward the jtable 62 to fold the edglge of the material. The movement ot said side wipers is controlled b v nani slots 79 in the lace portion ol' said uprights 52 secured to the o neratirg ring, and the movement oi Ye Ycornei' wipers is controlled by V e cam sets Si? in the in .L of the uprights o2 secured lo the operating ring.

A rectangular shaped plate is arra` on suitable supports lion: the base the machine, and terms nare of the framework of said machine.

Tiper operating` members 82 are arranged in grooves 83 in said frame, and have pins 84, which extend .dewnwardlY therefrom through slots 85 in the trame S1 and into engagement with the walls oic the earn grooves 79 and 8() in the uprights 52and 52. lonnecting rods or strips 86 extend between and are secured to said wiper operating members 82 and the wipers 77 and 7 8.

lly the arrangement oi the cam grooves 79 and 80, it is seen by the reciprocating angular movement of the operating ring that the wiper operating; members 82 will be reeiproeated with respect to said frame 8l, and consequently reciproca te said wipers toiard and awali7 from the material arranged on the table 62. Said connecting rods or members 86 are termed with slots S7 therein, through which screws 8S are passed to secure said connecting rods to the wiper oper-l ating members 82. By the arrangement'ol this slotted connection the connecting rods may be moved in toward the centre of `the machine and away from the center ot the machine to adjust the wipers it'or various dimensions of material to be :folded7 and thereby lorins an adjustable feature oit the machine.

The wipers arc supported von and between wiper supports. which in turn are arranged on the longitudinal cross bars 89 and transverse bars 90. Said bars are tongued at their extremities, and are slidably urranged in grooves 91 formed in the inner part ol' the rectangular iframe 8l. Said bars are so arranged that thejyv may move with respect to each other; that is the bars 9,9 may be moved with respect to the bars 39, or the bars S9 may be moved with respect to the bars 90, and provide means for spacin the wipers for various dimensions olf material to be folded. Rods 92 are arranged in spaced relation beneath the bars and are seI ed to the ends of said bars by bolts 953, and other rods are extended beneath the 99, and are similarlg7 secured to the en olf said bars by nie-uns ot bolts 93, Said rods 92 and 9i form in elllect parts ot the `said bars S9 nd 99, npon which the wiper snpports are adjustablv arranged and roi-ni means to stillen said bars.

The wiper supports rr slidably arranged on said bars S9 and 90, and rods and 911i, and comprise the blocks 96 formed with space apart upright ears 97. 'which in'oride grec' s in the top 'Faces of' said iblocl; 9G

arranged to receive said cover plate 9S is arranged over 'ne top ot said lu s 97 and secured thereto by suitable serene. und thereby termi; n' enelosing` said plaies 99 and 99 within f vriper supports. l susanna-.h as certain of screws which secure the cover plate 9': the wip r supports must pass through the longitudinal bars @I9 or the tra: bars 99 in order to engage with the lugs of the wiper support, it is necessaryv that slots 99 be formed in s id bars to permit the desired movement ot e wiper support.

ports.

As a screw 100, securing the cover plate to the bloclr 96 passes through the transverse bar 90 to engage the block 96 and said block must be arranged for movement along said bar 90, it follows of necessity that a slot must be formed in said bar to permit such movement. ln the same manner, a second screw 101, which passes through one of'said longitudinal bars 8S) must also operate in a slot to permit the desired movement of said wiper support along' saidgbars 89. 1t may beV seen that in the provision of such` an adjustment'I the wipers may be moved toward or away from thecentre of the machine to thereby adjust the machine for operation upon material of various dimensions.

The side wipers 77 are formed with tapered edges 102, which engage correspondingly tapered grooves 103 in the cover plates 98 of the wiper supports, which form means whereby the wipers may be reciproeated to and form the center of the machine, and also form means preventing the ui'iintentional removal ot said wipers from the wiper sup- As said wiper supports are moved from one adjusted position to another to accommodate the machine for operation upon material of various sizes, it is seen that the wiper suitable for one size of material will, in the new adjusted position of the wiper supports, be either too small or too large for the machine in its new set position; and, therefore, separate wipers must be supplied for every size of material which may be operated upon bythe machine.

rlhe corner wipers 7 8 are similarly formed with tapered sides 1011, which are slidably arranged in correspondingly tapered grooves 105 diagonally arranged in the cover plates 98 of the wiper supports, and are ad justably connected to the corner wiper operating members by means of the connecting rods S6, as has been previously described. The wiping' end 106 of the corner wipers is recessed or curved in form to approximately conform to the corner of the desired of the article operated on.

Said adjustable longitudinal and transverse bars 89 and 90 form means defining the dimensions ofthe folded material. The dimensions of the space enclosed by the opposing); edges of said bars is arranged to be but slightly `greater than the dimensions of the extended forming' plates which are adapted to be inserted therein for the folding of the materialaid increase of dimensions being merely that necessary to accommodate the material to be folded. In the operation of folding the material, the clamping plates force of the material into the space between the bars and the edge of the material is bent upward by said bars. The wipers are arranged to be inset from the edge of said bars p fevious to their wiping operation.' By moving,` the bars toward or away from each other the size of the opening` bounded by said bars is varied for the folding of material to differing;` dimensions.

In the operation of the machine the side wipers are first moved into operated position to fold over the side edges of the article, and then the corner wipers are moved into operated position. After the side wipers have operated to fold the straight sides of the material a superfluity of material is gathered at the corners which in the folding movement of the corner wipers forms wrinkles, whici. must be t ken care of and folded firmly and securely down over the edge of the material. For this purpose it has been found to be of advantage to form the wiping edge of the corner wipers with a number of small slots 107 into which the wrinkles of the material in the corner foldoperation are adapted to enter. Additional means are providedfor foldingthese wrinkles to the main body of material after the main portion of the corner has "been folded. These means comprise a spring` 108, which is secured to the corner wipers by suitable means, and which has a number of teeth 109 which are arranged within the slots 107. A rod 110 is extended over the corner wipers and secured by means of screws 111 to the wiper supports. The spring 108 is arranged with an upwardly bent portion 119l under which, in the eX- tended position of the wiper, said rod 110 is adapted to lie; by which arrangement the teeth 109 of said spring' are permitted to occupy the lowest position in the slots 107 .of the corner wipers.

1n the withdrawn position of the corner wipers, as shown in Fig. 12, said rodv 110 serves to move said spring upwardly, and to partially withdraw the teeth 109 from the slots 107. As said corner1 wipers are moved inwardly in the process of folding the corners of the material.y the teeth of said springs are maintained in elevated position terial is folded and the wrinkles form in the slots 107. Upon a further movement of said corner wipers, the bend 112 in the spring` passes over said rod 110 and thereby permits the teeth 109 ofthe spring to be moved into their fullest downward position, and to press the wrinkles out vof the slots 107 whereupon, after further movement of the corner wipers they are pressed ,by said rod 110, and the corner of the ma- Said presser head is formed as a trame, having the side and end portions 114e and 115 respectively, and is approximately over the material operated on. The end portions 15 oi seid presser head are lorned with gibs 116, which engage the tapered siirfaces 113 of the parallel portions oil said arms '70, and the presser head secured to seid arms by the set screwf' 117. Said arrangement of connection between the presser head and the arms 7'() terms convenient means for detachably connecting said head with ssi/l arms, and facilitates the exchange ot presser head et one sise tor a press head of another size to accommodate material ot' various dimensions. rihe presser head 71 at its lower portion carries -a clamping plate 118, which is of the general outline ot the presser head, and which is secured thereto by rivets 119 and maintained in spaced relation trom said presser head, whereby a space is p 1ovided between the presser head and the clamping plate 118 in which the forming plates are arranged.

llor 'forming plates 120 are provided, the projecting portions of which are tapered to o, thin edge, and which are arranged at the iour corners ot the presser head. Said forming plates are each arranged to present a corner and approximately haltI of contiguous sides oit the folding edge, and in their extended position, as shown in Fig. 1G, are arrange-:3l to slightly overlap, in order that an unbroken folding edge may be deiined. Substantially parallel slots 121 are formed in said 'forming plates, and rollers 122 are arranged therein over certain ot rivets 119, which serve to secure the clamping plate to 'the p -r head. pi 'allel slots 121 erve es means` whereby the forming plates l lay be moved diagonally outwardly and inwardly.

lllithin the presser head the forming plate is provided with a reinforced portion or lug 123, which servos to stiften the plates And also provides a means for the engagement oi said plates with means to nieve said plates. rod is arranged in said lug iii, and is slid-ably e: ended through the presser head Tl, and serves as a guide tor seid forming plates in addition to the slots 121 in said plates, and also serves to engthen said plates in their extended po- Blocks 125 are arranged within the l t ierein which are arranged to move at subsantiallY right angles to the direction or movement of said forming plates. The lugs 123 ot said lei-ming plates bear upwardly extended pins 127 over which are disposed rollers 123 arranged .in said slots 126. A movement of said blocks 125 inwardly within said pres "er head serves to withdraw said jliorming plate simultaneously from extend ed position. Said hloclrs are arranged to be simultaneously operated by a slide 129 arranged within the perallel portion of said arms 7G. remote tended Said slide is formed at the end 'from the presser head with an eX ear or lug 130, through which is arthe operating rod 131 to which said secured by means ot set screw 132. .rm-id rofl 131 extends through and s slid ily arrangerL in a cross member 133 unitl arms at the presser head, and is slmably arranged in and extends through the rear portion G9 oit said presser1 frame, and serve as a means whereby said slide is moved to extend or withdraw the forming plates. spring 13s is arranged on said rod 131 between the lug 130 of the lslide 129 sind the connecting member 133 of the arms 70, and serves to normally press said slide 1.29 in a direction to extend the forming plates into their operative and fold defining position.

A. collar 135 is secr-.red on said shaft 131, ind engages with the end portion G9 of said presser iraine to limit the spring presser 'iov/ement oit' said rod 131. The elite 129 uformed with right angularly disposed :lots 13G. YPins 13T7 are upwardly extended in said sliding blocks 125, and have seranged in said slots 136 ot the slide. An outward movement olf said slide in the presser head serves to move said sliding blocks 125 inwardly, which blocks in turn operate through the slots 126 therein and the rollers 127 secured to the forming plates to move said forming plates simultaneously inward to the retracted position, and the reverse movement oit sail slide 129 operates in reverse sense to extend the forming plates into their fold doiining position.

The rod 131 is operated by the cani hloclr 139 bearing the cam surface 140 seeured to the sliding cross head 45. A pin 141 is secured to the end of said rod 131 by suitable ar las the forming plates are normally extended in their iold defining position, said cani suriace 140 is arranged to permit considerable niovem of said eross heed without operating said rod 131 Vto perinit the operation oil other )arts o'i the, machine; but upon continued movement oil the cross head, said am surface is arranged toinove seid rod 131 inwardly to cause the retraction oi the 'forming plates, and after said retraction the iiorming plates are locked in retracted position during subsequent operitions of component parts of the machine.

nasmnoh as the Yforming plates are in ei;- tonded position when the wipers are operated to iold the material over s id forming plates, and as the return movements of the component parts oi the elements thereof to condition the machine for a new operation are in exactly the reverse order to their initial opere. 'fion it is seen that the forming j presser trame.

plates may be in an extended position and moved upward while the wipers are also ex- `damaged it means are not provided to lock said forming plates in retracted position until the component parts of the machine have returned to their initial positions in readiness i'or a new operation.

Said locking means comprises a bolt 142 slidably arranged within suitable bearings 143 secured to the rear portion 69 ci' the A retractal spring 144, connected between said bolt and said trame serves to normally press the end ot said bolt intoa notch in said rod 131.

in the retracted position ot the forming plates said bolt 142 is moved under action of the spring 144 into engagement with said notch 145 and serves to lock said rod in the retracted position of the forming plates. Unlocking means are provided, which are adapted to'be operated only when the various parts of the folding machine are mover to their original and normal position. Said unlocking means includes an upright member 146 secured to the end of the sliding cross 45. The bolt 142 is provided with a downwardly7 extended lug 147 in which is arranged an adjustable bolt or screw 148 which extends in the path of movement of said lug 146. When said cross head has been moved by its operating cam into nearly its initial position, said lug 146 is adapted to engage the screw 148 and to retract the bolt 142 from engagement with the slot 145 of the rod 131, which operates the slide controlling the movement ot the *forming plates.

Said rod 131 and the slide secured thereto is thereupon returned to its normal position by the spring 134, and the forming plates are thereupon extended to the fold delining position in readiness for another operation. (li-easing means are arranged beneath the material table 62, and are arranged to eugage with the material operated upon r ing the completion ot the told. Said creasing means comprises corner supports 146 bearing creasing irons 149 and side creasing irons 150. Certain of said corner supports are arranged to be heated by some means conveniently shown by the electric heating coils 152 to thereby heat the creasing iron. lt is sumcient to apply the heating means locally to the creasing iron, as the heat will be conducted to the entire creasing edge more or less uniformly. Inasmuch as the machine is adapted to operate upon material et various sizes, and as tliecrease formed in the folded material conforms very closely to the edge oic said material, it is necessary that said creasing LLL means maybe arranged to accommodate thev various dimensions of material ope ated upon. By the provision of corner supports bearing creasing irons 149, and separate side creasing irons 150, it may be seen that the corner supports and associated corner creasing irons may be moved closer together or farther apart, and the desired shape of supports are arranged in pairs on the rods 154, and may be adjusted relative to each other along said rods. The bases oi said sup-ports' are formed with gibbed grooves 155 therein, arranged transverse of the length of the rods 154 and bars 156 with tapered edges to tit the gibs of said grooves, are disposed' within said grooves. The arrangement ot said rods 154 and bars 156 at right angles to each other, provides means whereby the supports may be adjusted inwardly or outwardly to Vprovide ifor the creasing or material to differing dimensions. Said corner supports are adapted to be secured to said bars 156 and rods 154 by means of the set screws 157. The creasing means, as a whole, is secured to the plate 55 by means having provision for the vertical adjustment of said creasing means with respect to said plate, whereby the depth of' the crease in the material may be adjusted.

For this purpose two blocks 15S are arranged on arms 60 or" said plater55, and are 'formed with tongues 159 which extend with-. in the slot 61 of said arms. Plates 160 are secured to the bars 156, and are formed with grooves 161 therein. Said blocks 158 are formed with tapered grooves therein, which correspond to the grooves in ,the plates 166.

TaperedV keys are arranged in saidV grooves and serve to unite said plates 160 with said blocks 158; and a movement of said keys with respect to said blocks andV plate, serves to adjust cthe vertical position of the creasing iron. The keys 162 are formed with downwardly extended ears 163, which lthe groove 164 oi"y a bolt 165 threadeif. within the blocks 156. ly turning the bolt 165, the lrey 162 may bei moved within the grooves within said rplates 160 and blocks 158 tovadjustl the vertical position of' the creasing iron.

Bolts 166 extend through said plates 160 l' and blocks 158 Vand terminate in wing nuts 167, which engage the arms 60 and serve to clamp the creasing iron in any adjusted position. The creasing irons are arranged to be moved into engagement with the tolded edge ot the material during the latter part ot the folding operation. For this purpose the end of' said arms 6() oft the plate 55 are formed with a cam groove 168 therein, the

The shape ol the cams is such that during a eertein movement of the operating ring7 ythe plate is maintained. stationery and is supported in its normal position by its engagement with said pins 169.

When the operating ring 49 has reached the position which it is desired that the creasing iron he brought into engagement with the materiel operated upon, the shape of the cam grooves is such that the pin 169 raises seid plate 55 end thereby the creasing iron into engagement with the ifo-rial 'operated upon, end seid creasing iron is held in snch engagement during the passage ot the second dwell )ort-'ion of the @ein )oth 43 ov the cam roll 47 of the cross-head 45 end i'or a snil'icient period. of time to obtain zt good crease. Upon the reversal of movement of the operating ring' 49 the plate 55 is moved downward to itsoriginei position.

In the normal arrangement of the component parts ot the machine with Ithe clutch thrown ont, the presser head is raised from engagement With the material table, and the 'orming plates are extended-to define the :foldingu edge, end the wiper plates are Withdrawn. The material to be folded is placed on the 'table nnder the elainping'plate, and the clutch lever is thrown to conse the engagement of the clutch With the driving mechanism. The cam 42 consequently revolves and cansesthe cross head 45 to move transversely of the machine, thereby transmitting the motion to the operating ring 49. The movement of the operating ring 49 cerises an immediate downward movement of the cross connecting member 74 because ot' the engagement ot' the pin 75 carried thereby with the steep part, 179 of the cam ejroove 7 6, `and thereby censos the presser Atraine to descend and move the clamping plete into engagement with the materiel on the *.bfie 6i), :ind to secure said materiel to id lieto. The cani sha-oe is so :wronged that the trible 62 is niort d-owniveiid to some point belenY the wip-ers 71,

and the edge of the material is bent upave-rd hy seid bars 89 end 90. The com groove 'r6 contolling the nio.'en'ient` ot seid pressi'i ifi-eine is provided vith e. dii-fell portion 171j whereby the presser freine nniv remain without motion upon the continued motion of the operating ring); 49 in originel direction. The side Wipers are noiv moved inward by the cams 79 arranger in the nprights 52 secured to the opereting ring, and serve to fold the mel over the extended 'forming plates. A 1er movement of the operating ring es vthe operation of the corner wipers through the cani grooves 96 errenged in the nprights 52 over the extended forming plates.

The dwell portions 172 and 173 oi said cam grooves 7 9 and 80 `are oi? such. a. length that the presser freine may be moved into engagement with the 'tehie to cle-.mp the me teriel thereto7 Without a movement of the side Wipers; and the dwell portions 178 of the com grooves S0 :tre of such a length that the side Wipers ere operated before the corner Wipers.
